Ideal Security Inc. SKPHC Plastic Cap Washers for Nails or Screws Box of 500, 7/8 Inch, White, Count

Perfect for hanging foam board. Quality pieces that work perfect.

Here was my problem. I wanted to hang mug hooks under standard melamine kitchen cabinets. The white vinyl coated hooks that are big enough to hold my large handled mugs are just a bit too long and are going to break through the shelf. I thought of vinyl washers, but needed them to have a very small hole. I found these and after reading the questions and reviews, took a chance they would work. Not only did they work perfectly, they don't look obvious! They just look as though they are part of the mug hook. Even better, they cover that little bit of jagged edge that still shows after the hook is screwed in. I've replaced the other existing hooks in my kitchen (and elsewhere!), using these perfect washers. I used two washers for the depth I needed to keep the hook from breaking through the shelf. The hole is small enough that all I needed to do was screw the washers down to the end of the hook then screw the hook itself into a small pre-drilled pilot holes. I've included the link for the hooks I used. Bought them from amazon as well!  Metal Screw Hooks,Valar Dohaeris 10 Pieces 2 Inch Vinyl Coated Ceiling Hooks Cup Mug Hooks holder,Multinational Hanging Hooks for kitchen Ware,Lanterns,Decorative Lawn Garden,Christmas Lights,White

I bought this with the intention of enlarging the center hole so I can use it for visibility marker at the edge of a decking. I fastened the caps with screws for permenancy. Time will tell if the plastic is UV resistent enough to last. Having 500 in a box, I can afford to replace them if necessary.

Used to secure foam insulation to sill plate. Far more than I needed, surprised I had to ship in from Canada, kinda spendy for what they are, plastic is a little thin, diameter a little small. Having whined about all that, they work just fine and are handy to have around, I am sure I will find other uses for them.Only real (kinda) con is that the center hole was a little small, I was using #9 x 5" screws, all I could easily find locally at a price I wanted to pay. Could not easily push the screw though the center hole, easier to sit at kitchel island and pre-assemble screws through washers with a small screw gun. Would buy again.

All good I use them for insulation and house wrap. I buy without nails because I use so many different sizes.

Great

Works great with the small headed deck screws and ridged foam insulation.

Easy to use and very effective

Good quality

Using them to screw up 2” styrofoam with deck screws. These are exactly right for the job and are inexpensive.

Was as described and very useful pitting up sheets of insulation.

These are so much better for installing the hard foam boards , u use screws as opposed to the washers with nails in them, it never fails that u might have to remove an insulation board at some time and if u use nails your going to destroy the board, this is my second box of washer, these are difficult to find as well

If your looking for washers to hold down house wrap or roofing underlay that's stronger than staples...this is your product.I was tired of my wrap coming off and I wanted plastic washer I could screw down ( not nail) I also didnt feel like paying hundreds of dollars.This product ticks all the boxes. They are inexpensive, durable and make for a better overall quality job. I highly recomend them.
